what changes happen to object when they are shaped? example paper or plastic bag.?
Answer (1)
Answer:When objects like paper or plastic bags are shaped, they undergo physical changes. These changes can affect their appearance, structure, or function, but usually not their chemical composition. Here's a breakdown of what happens:--- 1. Change in Shape or FormPaper: Can be folded, torn, crumpled, or cut into different shapes.Plastic bag: Can be twisted, stretched, folded, or reshaped (e.g., into art, packaging, etc.).> ✅ These changes are physical, not chemical—no new substance is created.--- 2. Change in Texture or SurfaceShaping might make the surface smoother, rougher, or wrinkled.Example: Crumpling paper gives it a rough, uneven texture.--- 3. Change in Strength or DurabilityFolding or stretching materials can weaken them.Example: A stretched plastic bag may tear more easily.--- 4. Change in Function or UseShaping can give objects new uses.Example: Folding paper into a paper airplane or origami.Example: Twisting a plastic bag into rope or wrapping material.--- 5. ReversibilitySome changes are reversible (e.g., unfolding paper).Others are irreversible (e.g., tearing the paper or melting plastic with heat).---Summary TableProperty Affected Paper Plastic Bag Type of ChangeShape/Form Folded, cut, crumpled Twisted, stretched PhysicalTexture Smooth → wrinkled Smooth → stretched/thin PhysicalStrength Can tear more easily Weaker when stretched PhysicalFunction Used for crafts, notes, etc. Used for storage, wrapping FunctionalReversibility Often reversible Sometimes reversible Depends on methodLet me know if you want examples of chemical changes too, or want to compare shaping to heating or dissolving!
